I've three heavy duty 150mm random orbit Sanders, one of them is a Bosch GEX 150 body handled machine.

They've velcro backing pads and adjustable speed with the GEX 150 having two different orbit sizes depending on stock removal/fine finish. The fine finish setting is probably too small an orbit but the other would probably work.

I've a PEX Bosch and tried a Lake Country white pad with finishing polish to see if it would work (8 or 10mm orbit I think).
The pad didn't hold on very well at all and with a bit of pressure on tight curves it tended to move and become unbalanced.
I'd use it to apply a wax but it's what convinced me to get an RO unit.
Not sure if the backings are different for sanding pads and polish pads but the RO works perfectly with the same pad no movement.
Yours might be ok, nothing to loose in trying a pad.
